US power generation contractor and renewable energy company Blattner Energy has completed construction of a 20MW lithium-ion battery storage project.
The Lee/DeKalb energy storage system (ESS) in Illinois, US, is now providing the regional transmission organisation, PJM Interconnection, with the frequency regulation support needed for the area.
The project included Greensmith Energy Management Systems as the integrator of eight containers, 10 feet by 40 feet in size, housing 2.5MW of LG Chem lithium-ion batteries each.
Blattner Energy engineered the system, procured the technology and equipment, oversaw the installation and interconnection of the system technology, as well as completing the testing and start-up activities.
Stephen Jones, director of solar, Blattner Energy, said: “Battery storage will be a key technology in supporting the stability of our grid and the intermittency of some renewable generation sources.”
